1.1.1 NE20/20E
The NE20/20E router is grouped into NE20-2, NE20-4 and NE20-8 in terms of the number of
slots. The NE20E series router has only one type, the NE20E-8. The equipment structure and
the system of the NE20E are almost the same as the NE20. All of them adopt modular
architecture, providing many kinds of optional multifunctional interface modules such as
High-speed Interface Card (HIC) and Flexible Interface Card (FIC).
The NE20/20E series routers provide coherent network interface, user interface and
management interface as well as strong flexibility and configurability. The routers integrate
many emerging technologies, such as Multi-protocol Label Switching (MPLS), Virtual Private
Network (VPN), Quality of Service (QoS), traffic engineering, multicast, and user
management. The routers also support abundant link layer protocols. In networking
applications, as high-performance convergence devices, the routers can provide overall
service processing capacity and flexible network solutions, and thus effectively add the
network value and save the construction cost.
1.1.2 Architecture
Based on the TCP/IP structure model, the NE20/20E supports multiple data link layer
protocols, network layer protocols and application layer protocols, as shown in
Figure 1-1
